I An important object of this invention is] to providea device that will uniformly dis-.

1 tribute a lubricant in a thin even film to the, I grooved surface of cable sheaves for effectually lubricating the sheave contacting surface of cable lines as they are passed thereover. I v

Another object is to provide eration.

r Still another object is to provide a device] that is of inexpensiveconstruction, that will? distribute the lubricant in an even andeco-i nomioalmanner to the cablelines or sheave, surfaces, and which will'not be liable to vget outof order during its operation.

' s Further objects and advantages will be ap-Q parent-from the following specification, ref:x

As the elastic'periphery of-the distributing wheel contact's'at all'times with the grooved the friction that is generated during its move ment when not provided With lubricants 3 In Fig. 5 a modified form is illustrated in which the metal lubricant feeding Wheel 25 is provided With a rounded surface that engages the concaved annular groove 26 of the distributing Wheel 27, the groove in Wheel engaging at all times the cable line 7 during its operation and e'fiiciently lubricating the same. i V

In Fig. 6 a still furtherinodification is shown in Which the feeding wheel is dispensed with, a single Wheel 28 having an annular grooved rim contacting directlywith the cable line.

By providing a lubricant device and disposing the same in a position so that the lubricant is evenly applied to the sheave C011,

tactingsurface of the cable lines during their operation, or to the grooved surface of the sheave over which the lines pass, it Will be apparent that none of the lubricants so applied Will be thrown off the line or'sheave by reason of the centrifugal force generated by o the fast rotating sheave, and that by such application to the lines a large percentage lubricant will be absorbed, thereby adding greatly to their life. i p

What I claim" is:

- 1. A device for lubricating cable lines dur- 'ing their operation comprising a lubricant rese'rvoir,a feeding Wheel'having concaved threaded periphery, a distributing Wheel having a convexed elastic periphery e'ngaging the threaded surface of afeeding Wheel,

said distributing Wheel adapted to engage the grooved periphery of the cable sheav over which the cable line passes. V c 2. A device for lubricating cable lines during their operation comprising alubricant reservoir, a feeding Wheel having a concaved peripheral surface, said surface lhaving'a plurality of projectionsextending therefrom, a distributing wheel having a convexed periphery engaging the projections on the surface of the feeding Wheel, said distributQ ing Wheel adapted to engage the grooved periphery of the cable sheave over which the cable line passes.
